Vintage Stereo Receivers ~ Tuners ~ Amps

Kenwood KR-6600

Kenwood KR-6600 ('76-'77) 60W x 2  SOLD

This beauty is in excellent cosmetic and working condition.

In 1976, it was second from the TOTL in power...the KR-6600 is a jewel of vintage history.
Easily capable of running two turntables, three pairs of speakers and, by removing the jumpers, it makes a fantastic preamp.
The 6600 has a double protection system which offers complete output stage protection as well as loudspeaker isolation; Acoustic controls provide +6dB at 50 Hz and 800 Hz. 

The amplifier board was pulled for inspection and all the connections were thoroughly cleaned.  

Service on this KR-6600 included bridge rectifier replacement, installation of thirteen (!) brand new lamps and, as with all our gear, switches and pots have also been checked and cleaned....bias and DC offset have also been set.  

This is one very clean, very powerful and awesome piece of vintage history. 

With its many lights of different colors, it is very cool to just simply look at as well as listen to its excellent sound stage.  The KR-6600 is one of those receivers that has nothing but glowing reviews from those who have been lucky enough to own one.  


Kenwood KR-4070

Kenwood KR-4070 ('78-'79) 40W x 2 $185

One of Kenwood's most popular receivers ever made, this very cool KR-4070 with upgraded warm blue LED lamps for the FM glass and meters, has a strong tuner section and excellent phono stage. The overall sound is sweet and transparent with many numerous great reviews on the web.  Built to compete with comparable mid-sized Pioneer, Sansui, Yamaha, etc and, according to a few online discussions, outsold them all. It  features a wide band power with the same low distortion amplifier and high performance FM tuner you expect from Kenwood .Capable of driving two pairs of speakers, it has the usual aux, phono and  tape inputs/outputs.Features: 40 watts per channel, (min. RMS both channels driven at 8 ohms, 20 - 20,000 Hz, with no more than 0,05% THD), 
Direct-coupled pure complementary amplifier circuit, quietest phono section in its class: 83 dB S/N, 3-gang tuning capacitor and FET front end for high FM sensitivity (2.0 µV ) with low distortion, PLL in FM Multiplex for improved stereo separation, Large signal strength and FM center-tune meter and FM Auto Muting.  In other words, a lot of great stuff in a beautiful vintage receiver.

Note: This Kenwood KR-4070 has a black metal case.  The wood case shown in photo is for display purposes only and is not included.

Kenwood Super Eleven (1981) 125W x 2​   Not For Sale

Here's a link to video of an operating Super Eleven (courtesy of Tom Jordan at HiFi Collector)
http://hificollector.blogspot.com/2017/01/kenwood-super-eleven.html


The​ most rare and coveted ​monster ​Kenwood​ Super Eleven high speed DC stereo​​ receiver is one of the last of the truly big and well built receivers made during the golden age of HiFi​.  

At a conservatively rated 125 watts per channel and ​absolutely ​all the bells and whistles anyone could ever want rolled into one​ super-sized (over two feet wide) black-face, walnut veneer case, it demands your attention...it's that impressive.

The Super Eleven has triple voltage selection, easily handles 3 pairs of speakers, two turntables, two tape decks, aux, and so much more.  The FM analog dial plate has gorgeous blue lights and stretches across the front and is part of the analog/digital tuner combo that works flawlessly.  The blue LED frequency numbers are in correct alignment with the analog dial pointer.  When using echo and time delay functions, the center of the front display lights up with digital bands in cadence with the amount of echo/delay of your choice...a dazzling light show indeed!

The built in 5-band equalizer is perfect for controlling accurate sound reproduction across the sonic spectrum and is much better than the standard bass/mid/treble knobs​ found on most receivers.  The equalizer can be shut off to allow the receiver to function in a completely flat mode.  Another of its many fine features includes adjustable reverb and time-delay to simulate live concert hall sound.  It also has a mic input to patch into recording or sing along with the music.

A true survivor of the receiver wars, its a strong tribute to the masterful Japanese designers from back in the day and is a solid piece of vintage history.


About Kenwood (Trio)...

Established in 1946 as the Kasuga Radio Co. Ltd. in Komagane City, Japan, in 1960 the company was renamed Trio Corporation. In 1963 the first overseas office was founded in Los Angeles.

In the early 1960s, Trio's products were rebranded by the Lafayette Radio Co with a focus on CB radio.

An importer of Japanese-made electronics Radio Shack (Realistic, Tandy Corp) was A&A Trading Co., and a bilingual Japanese-speaking manager from there established a company that would be the exclusive importer of Trio products.

The name Kenwood was invented by Kasuga as being the combination of "Ken", a name common to Japan and North America that had been tested and proven acceptable to American consumers in the name of Kenmore appliance (Sears) \, and "Wood", referring to the durable substance as well as suggesting a relation to Hollywood.  The brand recognition of Kenwood eventually surpassed that of Trio's, and in 1986 Trio bought Kenwood and renamed itself Kenwood.  Eventually, Kenwood merged with JVC in 2008 as JVC/Kenwood.

Pioneer SX-3600

Pioneer SX-3600 (1980) 30 WPC $165


Pioneer’s Fluroscan receivers were the last of the heavily-built Pioneers. The excellent-sounding SX-3600 is conservatively-rated at 30 continuous watts per channel (RMS) with low 0.05% total harmonic distortion. It has ample power for home use with any reasonably efficient speakers. The Fluoroscan display indicates power output for both channels.  Maybe not a powerhouse but certainly one of the best looking receivers that Pioneer ever made.  Timeless elegance with it's stunning front silver face design, blue digital meters and walnut veneer side panels and top.  This is a fine minty unit...faultless and sounds fantastic.

Pioneer SX-434

Pioneer SX-434 (1976) 15 WPC  $115


The "young 'un" of the Pioneer family of fine receivers, the Pioneer SX-434 is a mid-70s stereo receiver that, at the time, supplied state-of-the-art technology to the tuner and integrated-amplifier. 

The fact that SX-series receivers are still widely used today speaks to their superior build quality.

Of course Pioneer was the premier name back then and advertised in every magazine that catered to those even remotely interested in HiFi...especially Playboy and Stereo Review magazines.  Pioneer would make it seem that if you didn't have a Pioneer setup, you just weren't hip.

The very cool SX-434 with its famous "Pioneer blue lights" has inputs for phono, aux, tape loop, plus switched and unswitched AC outlets. It is also possible to plug in a microphone and use the mixing circuitry together with a record, tapes or FM. 

Cosmetically, the face plate and wood cabinet are in near perfect condition - it almost looks brand new.

This originally sold for $299 - about $1,500 in today's dollars!!

About Pioneer...

Not much needs to be said about Pioneer other then the simple fact that the name is known worldwide for above average quality and excellence in high fidelity component design.  They were the unchallenged leader in stereo advertising and marketing in the 70's.  Back in the day, Pioneer made it clear that if you didn't have a Pioneer stereo system in your house (or college dorm) you just didn't have the right stuff.

Onkyo TX-2500 MKii

Onkyo TX-2500 MKII (1980) 40W x 2  $220 (mint)


This was the first stereo receiver with quartz-synchronization for the FM band.  Even though its predecessor, the TX-2500 was a successful Onkyo lower/middle class receiver, Onkyo decided to redesign the 2500 so the MKii version was optimized.  Upgraded components packed into the same chassis resulted in an additional 13 watts per channel more than the first version and was rated at a conservative (and honest) 40 watts per channel.  
And, for the display scale, they used real thick glass. With its already desirable industrial design, this was an added expression of timeless elegance. It's a heavy receiver with solid high power, enough to drive 3 pairs of speakers.  The trademark look of this series, the rosewood veneer on metal along with the four hex bolts holding the front glass, gives it a "top shelf" appeal.
Onkyo was so pleased with the overall success of the TX-2500MKii that, out of the hundreds of products they designed all that time, the TX Series were the featured receivers on the print sheets for their 70th Anniversary.


About Onkyo...
The word Onkyo translates as "sound harmony".  Starting out in 1946, Osaka Denki ONKYO K.K. is established and begins manufacturing phonograph pickups. The CP-1000 turntable was the first product to bear the ONKYO brand.  They also manufactured integrated stereo systems throughout the years but they majored in turntables, early amps, preamps, stereo receivers and also the cassette tape format beginning in 1981 with the TA-W800, the world's first high-speed dubbing, double-cassette tape deck with a wide variety of tape-editing functions.
They hit their high mark in the late 70's with the TX-xxxx series of stereo receivers, tuners and amps.  Onkyo kept pace with, and in some ways exceeded, the strong competition from Pioneer, Sansui, Marantz, Optonica, etc.  The stereo wars of the 70's yielded so many great products and Onkyo is right there with the best of them.
Today, Onkyo is still a global brand and their Integra series is well respected.

Fisher CA-880 & FM-660 & CR-125 & MT-6420

Fisher CA-880 integrated amp (1981) 100W x 2  $225 reduced system price

(includes FM-660 tuner, CR-125 deck and MT-6420 turntable)


This Fisher *Studio Standard CA-880 integrated amplifier is a strong, well built, well respected chunk of power built in-house by Sanyo at a time when they owned the Fisher brand.  

This CA-880 beast is definitely not the usual "rack system" amp that was so commonly found in department stores.  It's rated at a minimum 100 watts per channel RMS @ 8 ohms with a very good 0.09% THD.  A noted review online clocked one of these CA-880s at 114 watts per channel  @ 8 ohms.  

Two huge brightly lit vue meters, line/mic mixing input, black satin finish and white silkscreened lettering make this a real visual beauty.  As an added bonus, we recently replaced the "dreaded" Darlington power modules, so...no worries there. 

So, the 880 has an excellent reputation just by itself but, when combined with the included matching FM-660 tuner (with digital quartz locked tuning and push-button electronic station search bars), CR-125 cassette deck and MT-6420 semi-automatic turntable (see photo) it's a very beautiful system...with a LOT of power!


*Note: 
The Fisher "Studio Standard" series were developed by Sanyo after they took over the flailing Fisher brand in the 70's.  Of course the name "Fisher" is synonymous with high fidelity leadership since the 60's when Avery Fisher turned the audio world on its ear with his early tube units (like the famous Fisher 500C and others).  Alas, all things must end, Avery Fisher sold his company and, over the years, the brand has both flourished (to some) and floundered (to others).  It's generally agreed that most of the Studio Standard gear made by Sanyo (from the mid-70's to early 80's) is well made.
